Sextus (abbreviated Sex., the feminine form is Sexta, not to be confused with Sixtus) is a common ancient Roman praenomen. It probably means "sixth" (cf. Latin sextus, "sixth"). Parallel praenomina are Secundus, Tertius, Quintus, Septimus, and Decimus. These names don't necessarily denote the order in which their bearers were born. Among those named Sextus are: Sextus Roscius Sextus Pompeius (younger son of Pompey the Great) Sextus Pompeius (relatives of Pompey the Great) Sextus Propertius Sext… (More on Sextus)
